Abstract
The utility model discloses a coupler dismounting device which comprises a cross bar, a threaded rod, pull arms and pull jaws. The threaded rod is perpendicularly fixed to the cross bar. One end of the threaded rod is provided with a through hole, and the other end of the threaded rod is a push head. The pull arms are perpendicularly installed on the cross bar and the two pull arms are located on the two sides of the threaded rod respectively. The extending direction of the pull arms is the same as that of the push head end of the threaded rod. The length of the pull arms is larger than that of the threaded rod. The pull jaws are perpendicularly installed on the two pull arms respectively. The two pull jaws are located on the same horizontal line, and the extending directions of the two pull arms are opposite. The push head of the threaded rod is higher than the horizontal line where the pull jaws are located. The coupler dismounting device is simple in structure and low in cost, and hardly generates lateral force; the phenomenon of unhooking will not occur, so working efficiency is high; the distance between the pull arms can be adjusted, and the coupler dismounting device is applicable to different sizes of couplers.
Description
Technical field
The utility model relates to a kind of provision for disengagement, particularly a kind of detaching device for coupling.
Background technology
Existing detaching device for coupling is mostly Three-claw pull-horse, but there is following problem in such device: 1, one end of drag hook is hinged on guide pin bushing, and cheicers is less than 90 °, therefore when the shaft coupling being disassembled is applied to pulling force, always produce a side force, unhook phenomenon easily occurs like this when dismounting; 2, the adjusting range of drag hook is limited, so can not be applicable to the needs of larger diameter dismounting coupling; 3, when the larger shaft coupling of needs dismounting, the horse of drawing that use large-size, its complex structure, cost is higher.
Utility model content
It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, and without side force, is applicable to the detaching device for coupling of various sizes shaft coupling.
For achieving the above object, the technical scheme that the utility model provides is: a kind of detaching device for coupling, comprise cross bar, screw rod, torque arm and pulling claw, and described screw rod is vertically fixed on cross bar, and one end of screw rod arranges a through hole, and the other end is top; Described torque arm is vertically mounted on cross bar and two torque arm lay respectively at the both sides of screw rod, and the bearing of trend of torque arm is identical with the bearing of trend of the first end of screw top, and the length of described torque arm is greater than the length of screw rod; Described pulling claw is vertically mounted on respectively in two torque arm, two pulling claws be positioned on same level line and bearing of trend relative, the position of screw rod top is higher than the horizontal line at pulling claw place.
Preferably, the top of described screw rod is hemispherical top.
Preferably, described screw rod was fixed on cross bar by its screw thread and mating of cross bar through hole internal thread.
Preferably, the two ends of described torque arm are provided with through hole, and one end is enclosed within on cross bar by through hole, place pulling claw in the through hole of the other end.
A technical scheme tool in technique scheme has the following advantages or beneficial effect: compared with prior art, structure is very simple for this device, and cost is lower; Torque arm is perpendicular to cross bar, and pulling claw, perpendicular to torque arm, does not almost have side force when dismounting couplers, there will not be slip phenomenon, has improved operating efficiency; Torque arm can move left and right on cross bar, spacing that can easy adjustment two torque arm, and the size that pulling claw exposes torque arm also can regulate, the convenient fixedly shaft coupling of different size.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be done to simple introduction below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Accompanying drawing 1 is the structural representation of the utility model embodiment;
Accompanying drawing 2 is the use state diagram of the utility model embodiment.
The specific embodiment
Below by specific embodiment, the utility model is further described.
As shown in Figure 1, the detaching device for coupling of the present embodiment, comprise cross bar 3, screw rod 4, torque arm 2 and pulling claw 1, screw rod 4 is perpendicular to cross bar 3, screw rod 4 was fixed on cross bar 3 by its screw thread and mating of cross bar 3 through hole internal threads, one end of screw rod 4 arranges a through hole 5, and the other end is hemispherical top 6; The two ends of torque arm 2 are provided with through hole, one end is enclosed within on cross bar 3 by through hole, places the both sides that 1, two torque arm 2 of pulling claw lays respectively at screw rod 4 in the through hole of the other end, the bearing of trend of torque arm 2 is identical with the bearing of trend that screw rod comes directly towards 6 one end, and the length of torque arm 2 is greater than the length of screw rod 4; Pulling claw 1 is vertically removably placed in the through hole of two torque arm 2 respectively, two pulling claws 1 be positioned on same level line and bearing of trend relative, the position of screw rod top 6 is higher than the horizontal line at pulling claw 1 place; The size of pulling claw 1 can be selected.
As shown in Figure 2, while using this device dismounting couplers, regulate the distance of 2 of two torque arm, to clamp shaft coupling, be as the criterion, with screw rod top 6, withstand shaft coupling, pulling claw 1 is arranged in the through hole of torque arm 2, prop up shaft coupling, shaft coupling is fixed.Through hole by lever through screw rod 4 one end, drives cross bar 3 to move thereby screw rod 4 is rotated, and can make torque arm 2 pulling claws 1 rotate, and shaft coupling is disassembled from axle.
Applied specific embodiment herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred embodiment of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
